More specically stated, an 1' theprovision, in a valve member, of an injector which is disposed, in `a fluid passageway of the valve member, or ,'which, if the injector iis sectional, `has'at least, one section disposed in said passagewayfor` creatingV a force eective to produce. an` inow of` ui'd 'through1 another passagewajvnr a i Other objects and advantages will become ap.` parent in the following description and' from'the accompanying drawing, in which: i Figures 1, 2 and` Spare `transverse sectional Vviews taken through a valve ,device embodying the features of `the invention and illustrating threedifferentoperative; positions. f: Figs. 4:,and 5 aretransverse sectional views ggthrough amodied formgof ,structure and showing-two positions of operation.`

This application is a division ,of our aforesaid patentwithA respect to the structure shown in Figs. 1, 2 `and 3, and is acontinuationgiin part as regards the `structures shown in ,FigSi 4 to 71 i posed as showninFig. 1, the fluid stream passes inclusive. i i

(Referring rst to. the-:form of valve-)device shown in Figs. 1, 2 and, 10 designates au valvef .l cate with the chamber 11.

l2 `has a transverse bore 161 by." which connection casing having an internal bore or 'cham-ber;` 11 `in which,` a valve-member `12, is disposed forY relative. movement, The particular structurefand formj of` these parts is not material. The casing-has.- a plurality of portstherein,` .threesuchgportsr indicated at 13, 14 and `15, `being shown in thisy embodiment. Thesegportsfof course, communi-l The valve member between two ports, foreira'mple those `indicated 13 and 15, maybe established as shown in Fig. 1`. Extending angularlyto the bore 16 is a second bore 17 by which the samey fluid flow may be had in a second position of the valve mem-` object resides in ber.` The port 14 .isarranged to `be placed in communication with Ythe vfluid` wstream; passing between the ports 13 and.15.by a portion of either bore 16` 011;.-1'7'dependinggon whether the ports 13 and 15 areconnectedby bore 17'or 16.` I In oury aforesaid patent Ythevvalve is'employeil` in connectionv with awaterssoitening apparatus and is operable .tocontrol the :circulatory ow through'a softeningA cycle, or througha regeneratingfcycle aswell `toprevent fluid.- flow. In said 'apparatus,rtherseveral ports `are so connected that in. the.v 1 regenerative. jcycle the port? 13` is an `inlet port for :hard water, the -portqllL is an inlet port for concentrated brine solution, andfthefport 15 is Vanoutlet port for` diluted brine fso1utin..lzAn inflow Aof concentrated brine solutionzthroughfport 14 `is effected by whatis termedrinjector'means .whichis 'carried bythe valve member 12 f and "lis, operable i .when said valve member `occupies ia? proper position `relative` to theiiow ofv the mainl stream. L,

i A4 preferred formrfof injector means comprises two sections, 'onef being a jetoriiice section 18 andthe` other an induction tube section 1-9, either of which, or both, may be mounted .on' the valve" member .12.. :"I'hefjet `orii'lce section in thisfinstanceisj aftubular member `having a tapering bore terminating insa restricted discharge i orice .20. :The 1 induction :tube section isv likewise a tubular member: having anA internal bore 21 flaring toward fthe ldischarge. oriceZO when the parts are `.operatively associated.

`As shown in Figs.l 1, 2 and 3, the-sections 18, 19 are both mounted on the valve-member in the passageway 17, thejetforice. section being arranged at one .endvof the, passageway to discharge inwardly .of the `valve ,member and; the induction tube f section `19` being located at the opposite end of `the 1. passageway to `receive the jetoffluid from theiorifice 20and direct the flow intok port 15. The passageway 16 opens. into the spacebetweenthe `two injector sections.` l `When thezpartsl of fthe valve device are dis,

directly!A through the valvemember `since thev injector means is inactively 'positioned withrespect to said stream."y In this position, if desired, the-.,sections, or` one s section, may `be, ar-

ranged toby-pass fluid4 from thepassageway 16 outwardlythroughthe port 14. i

" :When the valveymember i12 is shifted-into the" positionr shownV in, Fig. .2, ,circulationv through thev deviceis` prevented. Further shifting movement carries the-.parts into theirelation :shown in Fig.`

3 wherein ,thejet orifice section '18 isadjacent thefinlet. port 13, one part of passageway `lo ivormsanuct communicating withsport 14, `and the induction'tube section 19 is opposite port 15. The flow of `the main fluid stream into port 13, through passageway 17 to port 15 produces a member 12so disposed that,l the inducedflow vtion of the'sections offtheA injectormeans will determine the volumetric proportion of indrawn f fluid to the main fluid stream.

Figs. 4, 5 and Figs. 6, '7 show modiiied form of structure in which only one injector -rneans section is mounted on thefvalveI member-12. Referring to Figs. 4 and 5, .and with the reference v`numerals remaininguuncliange'd, the jet orifice section 18 is mountedV inthe valve member 12 to discharge into theinduction tube section 19 which is fixed in the casing 10 adjacent to the port l5.- Thepassageway 16 preferably follows' a` somewhatlzarcuate pathV through the valve member tolallow the jet orifice section to be located relatively close to'. the' cooperating induction .tube section while still providing communication between port 14Aand the space between'the injectorA sections. v

In thev structure .illustrated in Figs. 6 and :.7 `the jet orifice sectionis mounted on the valve casingl adjacent toport 13 for-discharging a jet of fluid into the induction tube section which is carried by thevalve-,member` 12. Otherwise,

vthe structure isV substantially the same as that shown in Figs. 4 and 5. A.

. In the twolast mentioned forms, the. structural arrangement is such that `the :injector means is operative only when the. main. fluid Vstream moves in one" direction .through 'the device. But-in the formshown in Figs. 1, 2 and 3,- the main now may be reversed and the valve isstill obtained.A Sucha relationship would be present, for example, if thevalve. member ,l2 were moved from: its position as shown inFig. 3. H 5

It .will be evident from. the .foregoing that `a novel valve device has been produced which is simple in construction, efficient in operation and which maybe used, not only in waterl softening apparatus, butrinfmany other -elds wherever it is'desirable to .introduce a fluid iiowby theV action of "a force created by the iiow of a ymain fluid stream.A l
